Treat's Upto 100,000 Litres

Our fastest treatment for clearing green pond water contains 3 times more bacteria than our best-selling pond treatment. The millions of beneficial bacteria that are included in this product target green and murky water and eliminate it for good.

Pond Klear Xtra is a natural pond treatment designed to clear green and murky water by using beneficial bacteria. With three times more bacteria than our original Pond Klear, it works effectively by binding particles together and sinking them to the bottom of the pond. Unlike other treatments that only temporarily address the issue, Pond Klear Xtra tackles the root cause, maintaining clear water by breaking down particles and preventing them from floating back up into the water column.

This treatment is suitable for both filtered and unfiltered ponds, though it may take a bit longer to show results in unfiltered ponds as the bacteria have more work to do. Typically, you’ll begin to see improvements within the first couple of weeks, with complete clarity usually achieved within three to four weeks. Pond Klear Xtra provides a long-lasting solution for clearer, healthier pond water.

Reviews

Did the job

"My pond had become very green during the recent hot weather. My usual treatments didn’t seem to be working. After reading the positive reviews I decided to try Envii Klear Xtra. It’s taken 7 weekly treatments but the water is now clear (the label does say that it can take 6 - 8 weeks to clear very green or murky water). I also cleaned the pond filter twice a week, as recommended. It was amazing how much sludge was accumulating in just 3-4 days). You need to be patient as positive results do take time, but I’d highly recommend this product."
